A more practical attitude is to start from the following questions:
o What do I want to know?
o What information do I need for that?
o What information do I have in my dataset?
o What information do I (need to) add using assumptions/theory?
These kinds of models are inherently subjective, so trying to be as
"non-subjective as possible" is not very productive.
